I am looking for anyone that can tell me what to be looking for if plants are stressed from to much heat they must show some signs of discoloring or spotting or color over all anyone here to help meso I know what I'm looking for lights are about 24" from top of plants just want to make sure I see it in time to fix the problem if the lights are to close thanks for the advice
Not entirely true friend, plants will wilt like they have been overwatered due to constant perspiration of leaves. Brown discolouring will also occur from higher intensity heat ( burning ). This is by far the most expensive and ongoing issue with indoor growers so don't feel alone friend , fans such as exhaust and intake are really the cheapest way to go, and also downgrading ur light source, plants will be better off with leas light then more light and heat stress so dnt be too stubborn about this. Hope this helps bro... -peace designerz
